Antennas
Two rod-type COM antennas are mounted to the airplane’s exterior;
COM 1 is mounted directly above the passenger compartment, COM 2
is mounted directly below the baggage compartment. These antennas
are connected to the two VHF communication transceivers contained
in the Integrated Avionics Units.
The optional blade-type DME antenna is mounted on the airplane
underside just aft, right of the firewall.
The optional combined loop/sense ADF antenna is mounted to the
underside of the airplane just aft of the main wing spar. The antenna
combines antenna signals into a single signal input to the ADF
receiver.
A sled-type marker beacon antenna is mounted to the underside of the
airplane below the baggage compartment and provides a signal to the
marker beacon receiver located in the GMA 347 audio panel. If the
optional air conditioning system is installed this antenna is located
below the baggage floor inside of the airplane.
The transponder antenna is located on the bottom side of the airplane,
just aft of the baggage compartment bulkhead on the RH side of the
airplane.
GPS 1 antenna is mounted directly above the passenger
compartment. If the optional XM system is installed, a combination
GPS1/XM antenna is installed in this location. GPS 2 antenna is
mounted just forward of the baggage compartment window. These
antennas are connected to the two GPS receivers contained in the
Integrated Avionics Units.
The optional Traffic System antenna is mounted just above the pilot/
copilot compartment.
If the Garmin GTS 800 Series Traffic Advisory System is installed, a
second blade-type antenna is located on the bottom RH side of the
airplane just forward of the baggage compartment.
The optional Weather Information System antenna is mounted directly
above the passenger compartment.
The Navigation antenna is mounted to the top of the vertical fin. This
antenna provides VOR and glidescope signals to the VHF navigation
receivers contained in the Integrated Avionics Units.
